Problems with trace tool (traversability condition barrier)

MarianoDiNapoli — Wed, 04 Jun 2025 07:30:03 GMT

Good morning,
We have a question regarding an abnormal behavior in the Utility Network Trace tool.
As shown in the attached image, when attempting to perform a Trace Connected with a Traversability Condition Barriers set, and selecting Asset Type as parameter Name, a dropdown list appears for the parameter Value.

However, under normal behavior, the Value field should remain freely editable. Moreover, the dropdown list provided does not include all the available Asset Type values present in the Utility Network.
Is this a known issue or an anomaly you're aware of?

Could you please advise on how to resolve or work around this?

Best regards,

Mariano

The trace tool loads a domain from the first class in the UN. Since there is no single domain with all Asset Types, it will never show a complete list of asset types. Do you happen to have a domain assign to the asset type field on one of your classes(Not in subtypes view, fields view)?

Hi Mike, thanks for your answer.
It's the first time that we found this behavior. In all other Utility network that we managed, we have never never seen a drop down list in the Value parameter if for the Name parameter we choose Asset type.
How do you mean with "first class in the UN". Do you mean fist class in order in the Content pane?
In any case, one of our GIS technicians has mistakenly assigned the domain at the field level for the attribute ASSETTYPE, for several UN datasets. We will now remove it.
Thank you!

- to be honest, I am not sure how it picks the first class. I think it might be the first class that has a domain, not sure if that is the first class of the domain network(assembly) or structure. I just know that a domain at the field level is shown in the dropdown. That is why use have the lifecycle_combined domains at the field level and lifecycle at the subtype. The combined version of the domain has values we want to use in a trace, but a feature should never be set to these values.

Now that you know this, you could make a domain of all asset types/codes and assign it to the asset type field and get a dropdown for that Network Attribute.

@MikeMillerGIS as long as all your asset type names are unique, and you remember to update it every time you add a new asset type.
